('Cl. 13G- 5) 4 Claims.

This invention relates to corn huskers, and particularly to means for coating the corn husker rolls with a fluid that will facilitate the husking operation particularly in dry weather when the husks are dry and brittle; therefore, the invention comprises a method as well as apparatus for facilitating the removal of husks from the ears of corn.

It is an object of this invention to provide means for coating a husking roll or husking rolls with a sticky fluid which will aid in the husking process, and it has been found in practice that a viscous fluid with a tar base, such as, for example, that known commercially as Noursite Picker Roll Grease, preferably thinned with kerosene, when forced through ducts leading to the surface of a roll of each pair of husking rolls is effective to accomplish the result, and therefore the invention comprises means for accomplishing the result, including a roll which has been designated as a perspirating" roll, associated with another coacting roll suitably mounted in coactive relation and suitably driven to effect the husking operation.

lt is a further object of the invention, therefore, to provide husking rolls arranged in pairs, one of which has ducts or channels through which the fluid is forced and discharged to the external surface of said roll, and the invention also ncludes novel means for supplying the fluid through suitable pipes to the interior of the roll or rolls.

It is a still further object of this invention to provide ccacting rolls arranged in pairs, one of each pair of rolls being yieldably mounted with respect to the other roll and preferably the roll which is not yieldably mounted is provided with the means for supplying the iiuid to it, as by this means tne connections through which the uid is delivered are stationary.

It is furthermore an object of this invention to provide suitable mountings for the rolls and to arrange one of each pair of rolls so that it may separate slightly from its companion roll to permit husks of different bulk to pass between them.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawing forming part of this application, wherein like characters denote corresponding parts in the several views, and in which:

Figure 1 illustrates a sectional view of pairs of husking rolls with means associated therewith for rotating the rolls and supplying uid to one of each pair of rolls;

Figure 2 illustrates an end view showing the connections for supplying fluid to the rolls; and

Figure 3 illustrates a sectional view of one of the rolls and parts associated with it.

It is to be understood that the rolls are to be mounted in a suitable box or frame and as these are well known structural features, it is believed unnecessary to show such a box.

In this drawing a double set of husking rolls I, 2, 3, 4 is mounted on suitable shafts 5, 3, l, and 8 respectively. The shafts 6 and l are journaled in rigid bearings on the frame 9, and the shafts 5 and 8 are journaled in bearings on rocker arms I0 and li, respectively, which are pivotally mounted intermediate their length on spindles l2 on the frame 9. A rod i3 extends through holes in the lower ends of the rocker arms ill and Il; on the rod are coil springs I4 positioned between washers i5 on the lower end of each rocker arm and washers lo on the rod, and the Washers i6 are held in place by cotter pins Il passing through suitable holes in the rod. The rocker arms and coilsprings cooperate to hold one of each pair of rolls yieldably against the companion roll of the pair. Each pair of rolls has serrated frictional surfaces which cooperate, when the rolls are driven in relatively opposite directions, to grasp the corn husks and peel or tear them from the ears. These stationarily mounted rolls 2 and 3 are what are herein termed perspirating rolls and are intended to function for conveying sticky fluid for coating the outer surface of the roll. In the present invention, each roll 2 or 3 is mounted in a bearing I8 of the frame 9 and said roll has a longitudinally extending channel I9 through which fluid is forced through a coupling 2i), to which a supply pipe 2| is connected, the said supply pipe 2l being in turn connected to a pipe 22 leading from a reservoir or tank 23 which may be suitably mounted on the husker. A simple bracket (not shown) rising from the frame may be employed to support the reservoir or tank, and a valve 24 may control the ow of uid from the tank.

It is shown that the roll having the channel is provided with lateral ducts or orifices 25 leading to the surface of the roll and it is through these ducts that the fluid reaches the external surface of the roll.` The end of the roll remote from the coupling 20 is mounted in a bearing 26, and a sprocket Wheel 27 secured on the extension or journal 28 of the roll meshes with driving means by which the rolls are rotated.

The movable rolls l and 4 have meshing gear wheels on the outer ends by which rotary motion is communicated to the several pairs of rolls. The bearings are protected or covered by a shield 29 so that the husked corn may escape thereover to an appropriate collecting means which are of well known construction in this type of agricultural implement.

While the rolls have been described as for husking corn, it is obvious that in this art they could be used as snapping rolls with the same effect and they wouid be efficient when coated in the manner stated herein. No indication of the materials entering into the construction of these rolls has been made in the specication, but it is obvious that they can be constructed of steel, wood, rubber or any suitable material such as is commonly employed in devices of this kind.

Furthermore, it isr to be understood that my invention is not limited to any particular fluid. Under some conditions, plain water is sufficient, while molasses, honey, or other sticky liquids may be used where available.

I claim:

A crop treating machine comprising a pair of coacting rolls adapted to rotate in rel tively opposite directions and having frictional su lfaces for separating vegetable materials presented to one side of said rolls by grasping certain materials therebetween and passing the same between the rolls, ieaving other materiais on said one side of the rolls, one of said rolls having a conduit therein passage meanu leading therefrom to the surface of said roll, meanc for supplying an adhering liquid through said conduit and passage means to increase the coefficient of friction of said frictional surfaces to improve the ability of said rolls to grasp certain material therebetween.

2. A machine for handling ear crops comprising a pair of generally cylindrical rolis spaced apart a dista-nce appreciably less than the diameter of an ear and journaled for rotation in relatively opposite directions and having cooperative frictional surfaces adapted to grasp vegetation therebetween and pass it between the rolls to separate the same from the ears, one of said rolls having a conduit therein and passage means leading therefrom to the surface of said roll, and means for feeding an adhering liquid through said conduit upon the surface of the roll to increase the frictional grip of the coacting rolls upon said vegetation and thus to increase the efliciency of separation.

3. A corn husking machine comprising a pair of coacting husking rolls having serrated frictional surfaces, bearing means in which each of said rolls is journaled, means for rotating said rolls in relatively opposite directions to grasp husks and separate them from ears of corn, one of said rolls having a longitudinally disposed conduit therein, a hollow coupling connected with said one roll in communication with said conduit, and means for supplying an adhering liquid to said coupling under pressure, said one rcll having a plurality of passages for conducting said liquid from said conduit to the surface of the roll, said liquid being of such nature as to increase they coefficient of friction between the husking roils and the corn husks.

4i. A corn husking machine comprising a pair of coacting husking rolls having serrated frictional surfaces, bearing means in which each of said rolls is journaled, movable means for supporting the bearing means of one of said rolls providing for movement of said one roll toward and away from the other of said rolls, resilient means for urging said movable roll toward said other roll, means for rotating said rolls in opposite directions to grasp husks and separate them from the ears of corn, said other roll having a longitudinally disposed conduit therein, a hollow coupling connected therewith, and means for supplying a sticky liquid to said coupling under pressure, said other roll having a plurality of passages for conducting said liquid from said conduit to the surface of the roll, to increase the coefficient of friction between the husking rolls and the corn husks.
